Implementation of waste glass in bricks for improving its properties

Abstract

Construction and building materials that are less harmful to the environment and the economy are made possible via the recycling of industrial and municipal trash. This is achieved through minimising trash and its related expenses and preserving natural resources. Reducing waste sent to landfills and the resulting air, water, and land pollution is only one of the many benefits of recycling. This literature review looks at the prospect of using recycled materials, namely soda-lime glass, as a partial substitute for natural soil in the brick-making process. Increases in prosperity and technological innovation have coincided with a corresponding rise in the importance of waste management issues. Consequently, environmental issues have arisen as a result of the proliferation of industrial wastes including plastics, glass (cullet), and grogs (fired clays). The recycling of garbage has environmental and economic advantages, and its disposal has garnered a lot of attention, as stated by Loryuenyong et al.
The European Waste Catalogue (EWC) lists cullet, or waste glass, from bottles and windows as a non-hazardous waste item having economic potential. Most commonly, cullet is used as an additive in glass reforming because of its low softening temperature. It is also a promising alternative cementitious material in cement and concrete production for use in road construction, glass foam production, and the porcelain stoneware tile and brick industries. However, burnt clay bricks have been used for construction from ancient times and continue to be used now, albeit their quality must be enhanced for use in contemporary buildings.
The sintering step in clay brick production involves the shrinking of clay bodies at high temperature, and because of the high need for energy in this process, chemicals called fluxes are commonly included. Cullet's potential to operate as flux encouraging the vitrification of bricks, resulting in increased mechanical resistance, greater density, and lower water absorption, makes it an attractive candidate for use in batch formulations that aim to reduce energy and fuel usage.
